spinketbraX

◼ spinketbraX[S] returns the X-component of the spin operator for spin S in the bra-ket representation.
◼ spinketbraY[S] returns the Y-component of the spin operator for spin S in the bra-ket representation.
◼ spinketbraZ[S] returns the Z-component of the spin operator for spin S in the bra-ket representation.
◼ spinketbraP[S] returns the spin-lowering operator for spin S in the bra-ket representation.
◼ spinketbraM[S] returns the spin-raising operator for spin S in the bra-ket representation.

◼ S must be an integer or a half-integer.
